Electrochemical Detection of Organophosphates Using Dual-Modal Enzyme-Based Biosensors.

ABSTRACT: Exposure to organophosphates poses a threat to aquatic ecosystems and the public due to their acute toxicity. The dangers caused by organophosphates motivate the development of technologies for prompt detection. Therefore, engineering a portable and compact device that can monitor organophosphate vapors is vital. Electrochemical biosensors present a unique solution for rapid and selective detection of organophosphates, as these sensors are small and sense in real-time. Herein, this study investigates a dual-modal electrochemical system for the detection of dimethyl methylphosphonate (DMMP), a model organophosphate. The enzymes phosphotriesterase (PTE) and acetylcholinesterase (AChE) were chosen for detecting DMMP vapors, as these enzymes chemically engage with the target substrate and prod
